IMPROVEMENT IN MANUFACTURING GLASS-WARE 'WITH HANDLS.

TO ALL WHOM IT MAY GONCERN:

Be it known that we, J. S. Arrnnuunr and T. B. Arrnnnunr, of Pittsburg,in the county'ot Allegheny, and State of Pennsylvania, have invented anew and useful Improvement in the Manufacture of Glass-Ware withHandles; and we do hereby declare that the following is a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification, in which- Figure 1 is a.perspective view of 'moulds which arc adapted for the manufacture ofsmall hand-lampswith handles. i

vFigure 2 is a dia-metrical section through alamp and its handle withintwo of the half sections ot" its mould.

Figure 3 is a side view of the product of the moulds shown in fig. 1.

Similar letters of reference indicate corresponding parts in the severalgurcs.

This invention relates to au improvement in the manufacture ofblown-glass lamps and other articles of blown glass requiring handlesupon t hem.

' Under the old process of making such articles as we have abovementioned, the work of shaping and applying the handles is a separateoperation fromthat of blowing the bodies of the articles, and requiresthe experience of skillful workmen, who are guided by the eye alone inthe performance of this part ofthe work.

The object .of our invention is to greatly facilitate the process ofmaking lamps and other articles in glass requiring handles upon them,and at the same time to produce such articles in a more perfect mannerthan hitherto, by providing suitable moulds in which the body of th'earticle which it is desired to make can be blown, and the handleproduced and attached permanently to it at successive operations in thesame mould, as Awill be hereinafter described.

To enable others skilled in the art to understand our invention, wewillj describe its construction and operation.

Inthe accompanying drawings we have represented 'one form of mouldsadapted for producing lamps with handles upon them, and from adescription of these moulds, andthe process of making the lamps, it willbe seen that other articles can be produced in the same manner by simplychanging the shape of the moulds, without departing from the principleof our invention.

A A represent two half sections ofthe mould, which are adapted forgiving shape to the lower portions of the body and handle ofthe lamp, G,and B B are-two half sections which are adapted for giving shape to theupper portionsfot` the body of the lamp and its handle.

The sections or halves A A are suitably hinged together, `and providedwithlhandles, C A@by which they can be opened and closed; and on top ofthese sections are elevations, which are adapted to receivecorresponding recesses in the bottoms of the upper sections B B', asshown in gs. 1 and 2, so that when the two sections forming thclmouldcomplete are put together they will be properly matched, and will beheld in place.

The upper halves, forming the upper section ofthe mould, are suitablyhinged together, and provided with handles, C C, likethe lower halves ofthe mould, and through the centre of this upper` section a. hole, c, ismade, which produces the neck ,or rim of the lamp, a s"ishowu in iig. 2.

In tig's. 1 and 2, a a', I b', and c e represent the matrix in which thebody of the lamp is produced, and g g g, y g' g represent the matrix inwhich the handle. of the lump is produced. It will be seen that thematrix for the 'handle is in communication with the matrix for the body.

The operation of producing the lamps with handles upon them is asfollows: We first close the two halves forming the lower section ofthe'mould, and pour hot glass into the matrix g g', which glasswill flowto the bottom of this matrix. The workman, during this last operation,prepares his ball of glass, which is blown round, or nearly-thc shapeofthe body ofthe lamp. This ball is then -introduced into the lowermatrix a, and the upper section of the mbuld adjusted in place vover it,after which the workman blows and expands the glass in the mould so thatit will conform thereto, and at the same time attach itself rinly to theexposed heated glass in the matrix g g, thereby forming the body of thelamp, and attaching its handle, J, to it at one operation. The mould isthen opened 11n-d the finished lamp taken out', for a. ijepeti'tionofthe process.

Having described our invention, whatwe claim as new7 and desire tosecure by Lett-ers Patent, iss--A A glass lamp, or other article inglass,l1eving :L moulded or cast handle and e. blown body, producedsubstantially as described.
